Description

Technical Field

[0001] The utility model relates to the technical field of rail lifting, in particular to a lifting mechanism for replacing railway rails. Background Art

[0002] Railway rails are an important part of the railway used to support and guide trains. They are made of high-quality steel and have the characteristics of high strength, wear resistance, and corrosion resistance. The design and laying of rails must be precise to ensure the safety and comfortable travel of trains. When railway rails are damaged, they need to be replaced with the help of a lifting mechanism.

[0003] Publication number CN218175445U proposes a lifting device for replacing railway rails. The device can fix the rails more quickly and conveniently by setting a hook assembly. There is no need to bundle the rails again. The rails can be directly clamped and lifted, thereby improving the work efficiency of workers in replacing rails.

[0004] The load-bearing rod of the above-mentioned patent is fixedly installed on the support plate, resulting in a fixed position of the entire lifting structure. When the position of the rail after lifting does not correspond to the railway installation position, it is necessary to adjust the position of the entire lifting device by moving the bottom universal wheel, which is cumbersome to operate and inconvenient to fine-tune the position of the lifted rail, resulting in low efficiency in rail replacement. For this reason, we propose a lifting mechanism for replacing railway rails. Utility Model Content

[0005] The purpose of the utility model is to provide a lifting mechanism for replacing railway rails to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lifting mechanism for replacing railway rails comprises a support plate and a lifting mechanism, wherein a fixed beam is connected to the support plate, a U-shaped moving frame is slidably connected to the fixed beam, a walking unit is provided between the U-shaped moving frame and the fixed beam, an angle adjustment component is also provided on the U-shaped moving frame, the angle adjustment component comprises a rotating toothed disc, and the middle part of the lower surface of the rotating toothed disc is rotatably connected to the upper surface of the U-shaped moving frame through a bearing, a load-bearing rod is installed on the top of the rotating toothed disc, and the lifting mechanism is located on the load-bearing rod.

[0008] Further: the walking unit includes a reduction motor, which is located on the front end outer wall of the U-shaped moving frame, and the output end of the reduction motor is connected to a rotating rod, on which a traveling gear is mounted, and a plurality of groups of tooth grooves matching the traveling gears are provided on the top of the fixed beam, and the plurality of groups of tooth grooves are meshed and connected with the traveling gears.

[0009] Further: the angle adjustment component also includes a support platform, which is installed on the rear outer wall of the U-shaped mobile frame, and a servo motor is connected to the support platform. A rotating shaft is provided at the output end of the servo motor, and a driving gear is installed at the bottom of the rotating shaft, and the driving gear is meshed and connected with the rotating gear disc.

[0010] Furthermore: a T-slot is provided on the rear outer wall of the fixed beam, and a T-slot is slidably connected with a T-slide block, a linkage rod is provided on the outer wall of the T-slide block, and the bottom of the linkage rod is connected to the rear outer wall of the U-shaped movable frame.

[0011] Furthermore: a plurality of groups of reinforcing ribs are arranged between the rotating gear disc and the load-bearing rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model can drive the travel gear on the rotating rod to rotate through the operation of the reduction motor on the travel unit. Since the travel gear is meshed and connected with the multiple sets of tooth grooves, the U-shaped moving frame drives the lifting mechanism on the top to move horizontally and adjust the position after the sliding limit of the linkage rod, the T-shaped sliding block and the T-shaped groove. The servo motor on the angle adjustment component can drive the driving gear on the rotating shaft to rotate. Since the driving gear is meshed and connected with the rotating toothed disc, the lifting mechanism on the load-bearing rod can rotate and adjust the angle. When replacing the railway rails, the lifting mechanism can fine-tune the position to ensure that the railway rails can be installed at the specified position without moving the entire lifting device, thereby reducing the workload and improving the replacement efficiency.
